ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 596,828, dated January4, 1898.

Application filed August 14, 1896. Renewed September 4, 1897. Serial No.650,664, (No model.)

To @ZZ when@ t may concern.-

Beit known that I, THoMAs J. REID, a citizen of the United States,residing at `Nashington Court-House, in the county of Fayette and Stateof Ohio, have invented a certain new and useful Improvement inRoller-Bearings, of which thefollowing is a speciiication.

My invention relates tothe improvement of antifrictional bearings; andthe objects of my 1o invention are to provide an improved rollerbearingof such arrangement and construction as to retain the rollers in perfectparallel alinement with the spindle and With each other, to provideimproved means for adjustment of the balls and rollers, and to produceother improvements which Will be more fully pointed out herein after.These objects I accomplish in the manner illustrated in the accompanyingdrawings, in Which- Figure l is a central vertical section of ajournal-bor; having my improvement therein. Fig. 2 is a sectional viewon line :t of Fig. 1, and Fig. 3 is a partial longitudinal section of amodified construction.

Similar letters refer to similar parts throughout the several views.

In carrying out my invention I employ an external case a, which is openat its outer end and which is provided on its inner end with an inturnedflange portion d. Fitting closely Within this external casing is aninner case, which is preferably composed of the sections b and I9',these sections being capable of a longitudinal movement Within saidcasin g for the purpose of adjustment, as hereinafter described. Theinner surfaces of said sections are made to taper toward their innerends, and each of said sections has formed in its inner surfaceand nearits outer end portion a slightly-rounded shoulder or bearing-surface h2.v

c represents an axle-spindle which is provided Withthe usual peripheralshoulder c' at its junction With the axle-body. The spindle c 4 5 itswithin and is suitably connected with the sectional sleeve. This sleeveconsists of an inner end section c2 and an outer end section c3, thelatter being in the form of a cap which embraces the outer end portionof the spindle. 5o The outer surface of each of the sleeve-sections c2c8 has formed thereon slightly curved or rounded bearing-shoulders o",Which, as shown in the drawings, are opposite the correspondingly-shapedshoulders b2 of the internal casing. Said sleeve-sections are alsoprovided on their outer surfaces With inclines corresponding With theinner surface inclines of the casing-sections above referred to.

Arranged about the sleeve-sections c2 and c3 are tubular rollers d, eachof these rollers tapering from its central portion toward each end orbeing shaped to conform to the taper of the internal casing andsleeve-sections. Each of the rollers d is provided With an endbearing-block CZ', said blockhaving, as indicated, a screw-threadedconnection With the internally-threaded end portion of the roller andforms substantially a continuation of the roller end. The extension orprojecting end portion of each of the blocks d has its outer surfaceprovided with a curved or cone taper, which is adapted to bear and runin the correspondingly-inclined surfaces b2 and c4 of the internalcasing and sleeve-sections. These end blocks also serve, as will readilybe seen, to strengthen and support the roller ends, While the centralportion of each of the rollers is strengthened by an internal partitionor bridgerring d2. As hereinafter described for the modificationillustrated in Fig. 3, the blocks d may be omitted and bearing-ballssubstituted therefor.

In Fig. l each of the blocks d is provided on its outer end portion Witha cone-bearing depression or recess which is adapted to receivebearing-balls e. Passing through each of the rollers is a central shafte', the inner end portion of which carries a cone bearingring e2, andbetween the bearing-surface of said cone-ring e2 and the end recess ofthe adjacent block d are arranged the balls e. Each of the shafts e isprovided with an inner end screw-threaded extension e3, which is iscrewed into a separating-ring f, which ring passes about the inner endportion of the sleeve. On the outer side of this separatingring isarranged a felt packing-ring f', the latter being embraced Within afollower f2. At its outer end the threaded extension of the shaft e hasscrewed thereon a cone bear- IOO v outer end of the case.

ing-block c and on the outer side of this block each of said shaftextensions pass loosely through openings in a separating-rin g g', thelatter being secured in place by means of nuts g2. Between the conebearing-blocks g and the adjacent blocks d are arranged bearing-ballsg3, corresponding with the balls e at the opposite ends.

7L represents an outer end boxing-cap, which by means of the screws h isunited to the Through the central portion of this cap is screwed anend-thrustreceiving and adjusting screw 712, and threaded in the innerend of said screw h2 is another screw h3, the head or inner end of whichhas loosely mounted thereon the central portion of a ball-bearing ring71.*. Between the ring 71,4 and inner end of the screw 72, is a bearingcone or ring i, and between said bearing-rings z' and h4 are arrangedbearing-balls 7o. The bearing-ring it is adapted to receive the endthrust of the axle through the cap or head c3 of the sleeve. r

On the outer end of the screw h2 I provide a lock-nut k2.

7o represents adjusting-screws which at intervals pass through threadedopenings in the cap-plate 7L and the inner ends of which are adapted tobear against an internal ring 7c3, which has its hanged peripheryscrewed into engagement with the outer end of the internal casing.

Owing to the fact that the rollers are made to taper from their centralportions toward each end and that the surfaces within which they bearare similarly tapered, it is obvious that the load or weight on saidrollers will tend to the center and that the tendency toward wear of therollers through sliding friction will be greatly reduced. The shafts e'assist in retaining the rollers in proper alinement, and owing to theengagement of said shafts with the channel-rings g and f they areretained in parallel alinement with the axle-spindle c and at properdistances one from the other. These shafts also take the place of thecage-bolts which are ordinarily employed to unite the channel-rings,such as are shown at f and g. These channel-rings serve to close theends of the cage. It is obvious that the ends of the rollers will bestrengthened by the bearing blocks or terminations CZ and that the ballsc and g3 will afford antifrictional end bearings for said rollers.

An inward adjustment of the inner casingsections is attained by amanipulation of the screws 7o', thereby admitting of compensating forwear on the balls and rollers and their raceways.

The inward adjustment of the sleeve-head c3 may be accomplished byrotation of the screw h2, the contact of said sleeve-head with theball-bearing ring h4 operating to adjust the rollers and to greatlyreduce the friction at the outer end of the sleeve-head. Theendthrust-receiving screw h2 and the parts which are attached theretoare, however, claimed by me in a separate patent application of evendate herewith.

In the modification illustrated in Fig. 3 of the drawings it will beobserved that I have substituted for the end blocks or strengtheningextensions d (shown in Fig. l) balls m. vOne of these balls is seatedagainst and partially within each end of each of the rollers, and theantifrictional bearing-balls e are retained in frictional contact withsaid balls m, as shown, while the shafts c pass through said balls. I

As is true of the blocks d', the balls mbear in the curvedbearing-surfaces or raceways G4. and b2 of the sleeve and casing, andowing to the fact that said balls are by means of the shafts united withthe roller said roller and balls become substantially as one body.

The adjustment of the balls and rollers is effected by proper rotationof the cone bearing-blocks g and nuts g2, all adjustments being effectedfrom the front of the box.

It is obvious that the end blocks or extensions d (shown in Fig. l) andthe balls m (illustrated in Fig. 3) perform substantially the samefunctions as bearing extensions.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

l. In a rollerbearing, the combination, with the external casing, theinternal casing and a spindle-sleeve, said internal casing andspindle-sleeve tapering toward their central portions and also formingraceways between them, of a series of bearing-rollers which taper fromtheir centers toward their outer ends and bearing extensions in the endsof said rollers adapted to the aforesaid raceways, substantially as setforth.

2.
